Embodiment approach
[0066] This specification also discloses another embodiment as follows: the lowest point of the edge of the upper opening of the rotating passage is located at one-third of the height of the heat dissipation lamp cup, and the highest point is located at two-thirds of the height; thus, the highest point of the upper opening of the rotating passage The height difference from the lowest point is one-third of the height of the heat dissipation lamp cup, which is exactly located in the middle of the outer surface of the shell. Practical and beautiful, it is beneficial to manufacture and shape.
[0067] In this scheme, the air outlet of the rotating passage is opened and enlarged as much as possible, which is more conducive to ventilation and heat dissipation. If the air outlet is small, the rising speed of hot air will be affected.
[0068] Such as Figure 10 As shown, the length L of the reinforcing rib along the circumferential direction of the annular band gap is greater than t...

Abstract
The invention discloses a light emitting diode (LED) spot lamp which comprises a lamp holder, a radiating lamp cup, an LED light emitting module and an optical lens module which are connected with one another in a matching mode. The center of the radiating lamp cup is a cavity, the radiating lamp cup forms an outer surface of a casing of the radiating lamp cup and an outer surface of the cavity, the slope of the outer surface of the casing of the radiating lamp cup is smaller than that of the outer surface of the cavity, and a base plate which separates the cavity into an upper cavity and a lower cavity from bottom to top is arranged in the cavity; a ring-shaped band gap between the outer surface of the cavity and the casing is spaced into a plurality of rotation through ways which upwards penetrate through the outer surface of the casing of the radiating lamp cup from the lower end of the radiating lamp cup; the LED light emitting module is installed on the bottom surface of the base plate located in the lower cavity, and the optical lens module is covered on the LED light emitting module; and the lamp holder is arranged at the upper end of the radiating lamp cup. The LED spot lamp has the advantages of being good in radiating effects, low in costs and easy to assemble and disassemble.
Description
technical field [0001] The invention relates to the field of LED lighting, in particular to an LED spotlight. Background technique [0002] LED light source is recognized as the most promising lighting source in the 21st century. Its advantages such as green environmental protection, long life, energy saving, high reliability, good light efficiency and small size make LED light source more energy-saving than traditional incandescent lamps and fluorescent lamps. Lamps, etc. have greater application prospects. [0003] With the development of LED technology, the high luminous efficiency, ultra-high brightness and full color of LED continue to develop and innovate, and its technical requirements for lamp design and application are getting higher and higher. How to improve the structure of lamps, prolong the life of lamps, increase the level of energy saving, solve heat dissipation problems, optimize optical design, and save production costs, etc., are the areas that the indust...
